new terms / synonyms for citrus terms

[Alercia, Adriana (IPGRI - Rome)]

Dear Pankaj,

Sorry, if this took time but I wanted to double check with one of the
world international expert on citrus, Dr Roland Cottin,  who provided
the following definitions which I hope will be useful for this exercise
which I think is really important for our community. They are as
follows:

QUOTE

In my opinion :
 
- Albedo = mesocarp of Citrus fruits, inner part of peel (skin, rind)
often spongious and almost always white (Albedo word come from Alba =
white)
- Flavedo = epicarp of Citrus fruits, outer part of peel (skin, rind)
that contains oil glands, and almost always brightly coloured (Flavedo
word come from Flavour)
- Pulp = common name for endocarp in Citrus fruits (also called flesh)
- Endocarp = Inner part of the citrus fruit, composed of less than 5 to
more than 15 segments and a central axis, less or more hollow
- Segment = type of bag in pulp which contains juice vesicles (also
called juice bags) and seeds (in case of seedy fruits)
- Juice bag = little bag, gathered in a bigger one (segment) that may
contains generally coloured juice. Some relatives to Citrus fruits have
"Juice bag" but without juice, only membrane !
UNQUOTE

Hope this helps and please do not hesitate to contact Roland should you
require further information.

Dear Adriana,

I did browse the literature and see that citrus community do call the
Albedo equivalent to mesocarp. If so I would take your word.

Whereas for Endocarp being pulp, is not very clear. Seems that there is
a very thin layer of endocarp (innermost epidermis) may/may not be
visible in the developed fruit.

The  citation at
http://www.chineseplantscience.com/earticle_read.asp?id=12171
refers that juice sac is a multicellular structure that develops from
the innermost epidermis of the carpel which I see is equivalent to
endocarp. This means that juice sac being a derivation cannot be
referred as endocarp. If you can confirm isn't the pulp equivalent to
juice sac.

Based on this can you provide us a definition of 'juice sac'.
